Most information is less than 5 years old. Most over that is outdated

couple of years old.

Oh no!

That is a very common misconception. The most important
observations date to the 1970s. It was ignored by the popular
Press which found a new ice age to be a more interesting story.
But if you look at the proceedings of the climate conferences
of that time you will find a different story.

The essential Physics was established well before that. The
effects of aerosols also have been understood since then.

Quantifying the combined effects on global temperatures
is the more recent work, and there remains a lot of uncertainty
there. But the uncertainty is about how much of a rise and
how fast, not the direction of future trends.

Mainstream science around the world has pretty well concluded that the
rise in CO2 is creating accelerated warming and nearly all of that
increase is due to mankind. The oceans are absorbing a phenomenal
amount, rather than releasing it, but we are still seeing a large net
gain.

Unfortunately the oceans are rapidly approaching saturation. Should
the
oceans stop absorbing CO2, the rate of rise of atmospheric CO2 will
jump to about 15 times the current rate.

As to China, they only took over the tile of most polluting "from us"
within the past few months. It's difficult for any complaint we make
about China to carry much, if any weight unless we clean house and try
to set a good example.

And they are going to take over in a very big way.

Note followups.
